Import doping region - Simulation object – Ansys Optics

CHARGE

The Import doping object allows the import of a user defined spatial doping profile. The location of the object is specified via the edit window.

NOTE:

Doping objects are only valid for semiconductor materials. Any conductor and insulator that overlaps with the doping objects will not get any doping value assigned to them.
Doping objects are additive. This means that in the areas where two or more doping objects overlap, the net doping is calculated as the sum of the doping values of all those doping objects. n and p type doping values are considered to have opposite signs so they subtract from each other.

Geometry tab

APPLICABLE DOMAINS: This can be used to limit the volume over which the imported object is applicable. The object will be applied only to the volume that has overlap between the original object volume and the selected domain.
DOMAIN : Select the target domain. The reference geometry is the surfaces of the selected domain.
SOLID : Select the target solid. The reference geometry is the surfaces that enclose the selected volume if the solid is a 3D shape, or the surface if the solid is a 2D plane.
ALL DOMAINS: The object will be applied to all the available domains.

USE RELATIVE COORDINATES: If this is enabled then the doping region will use the center or the CHARGE solver as its origin (reference). If disabled then it will use the absolute center (0,0,0) as its origin.

CURRENT DATA
- DATA SET : The name of the current data that is selected.
- SELECTED ATTRIBUTE : Select the target attribute from data set.
- PARAMETER: Lists the name of available parameters.
- SCALE FACTOR: Multiplies the dataset values by the scale factor.
IMPORT: Opens file browser to select data file. The file must be in Matlab format (.mat) and can contain a rectangular or unstructured (finite element) datasets. Once the file is loaded, the available datasets can be viewed and the appropriate dataset and attribute can be selected. The unit for the imported data should be in units of /m3.
AUTOMATIC RELOAD: Script command getresult, or saving the project, will cause CHARGE to check the modification time of the file given by import file path. If the file has been modified more recently than the dataset was last loaded, CHARGE will attempt to import the chosen dataset from the file. Automatic reload during project save will update the project as saved to disk, but is not guaranteed to immediately update the current project.
DOPANT TYPE: The dopant type can be n-type (donors) or p-type (acceptors).
